As her 2nd husband said of her, she was "the greatest courtesan of the 20th century ".
This forced me to look up "courtesan", which in modern terms is simply "whore to wealthy men ". The Wikipedia definition is enlightening ... for ages, when marriage was more for political than emotional purposes, a courtesan was a member of "the court" of a monarch, somewhat a trusted confidant and purveyor of inside gossip, and usually "eye candy" as well.
As daughter in law of Winston Churchill, wife if Randolph Churchill, close friend of Lord Beaverbrook (wealthy newspaperman, head of aircraft production for England during the war), and mistress of Averell Harriman (US envoy for filling war material to England during the war), Pamela was a critical conduit of information, between key power players.
After the war, she became the "world expert on rich mens ceilings", and at the end of that career married Averell Harriman, became a major Democrat fundraiser, and was appointed Ambassador to France by Bill Clinton ... no irony there! She died February 1998.
The link gives more detail, and the book gives more detail on her "mother in absentia" role to her son Winston Churchill the younger.
She trod (or "laid") a rather longer path to power than more current women who used their relationships to men of power for power ... Hillary Clinton and Kamala Harris being current examples.
The book gives a lot of insight into how the 1% amorally lives, and how many actual "women of power" got their power. I would not generally recommend it, however for Churchill aficionados, it does give another perspective.
I also "enjoyed" page 6 in the introduction; "Joseph Biden, chairman of the Senate Judiciary Committee that gabble of out of touch men that botched the hearings of SCOTUS nominee Clarence Thomas".
Biden has been "out of touch" for his whole career, and now in his waning years, he is out of touch with reality itself. An amoral nation gets the "leaders" it deserves.
